- I had a blue chip upcycler dumping into a tank belt, which resulted in all the legendary green chips when dismantled.
- I overproduced some chips for my starting-from-rare-egg Productivity Module 3 upcycler. The iron plates are created when recycling excessive green chips for copper wire for red chips.
- The Gleba science is the throughput, not the hoard.
- I've been upcycling rotten Gleba science and shipping them back to Gleba for legendary Biochambers, so I got quite a stock of that.
- I built my base in the middle of a lake so I stocked some landfills.
- War effort with biters left me some ammo stash. I held the line with rare railguns + legendary-ammo gun turrets for a while. Before that it was roboport-maintained minefield.
